What is the number one cause of species extinction today?
Also to know is, what is the leading cause of species extinction?
The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming.
Additionally, what factors have caused the extinction of some species of plants and animals? Habitat Loss Deforestation and urbanization combine to create two reasons why plants and animals become extinct. Deforestation is leveling forests to harvest the wood or create space for building or agriculture, while urbanization is the turning of once-rural areas into cities.
Also to know is, what causes animals to become extinct?
Species may become extinct because of changes in climate (i.e. the ice age), competition with other species, a reduced food supply, or combinations of all of these. Most natural extinctions are isolated events that happen over a fairly long period of time.
What are the effects of species extinction?
The loss of a predator can result in what is called a trophic cascade, which is an ecological phenomenon triggered by a predator's extinction that can also impact populations of prey, which can cause dramatic ecosystem and food web changes.
